Jupiter

Jupiter is the fifth planet from the Sun and the largest planet in the Solar System. It is a gas giant with mass one-thousandth of that of the Sun but is two and a half times the mass of all the other planets in the Solar System combined. Jupiter is classified as a gas giant along with Saturn, Uranus and Neptune. Together, these four planets are sometimes referred to as the Jovian or outer planets. The planet was known by astronomers of ancient times.

 * The star [Tycho's supernova] was at first like Venus and Jupiter, giving pleasing effects; but as it then became like Mars, there will next come a period of wars, seditions, captivity and death of princes, and destruction of cities, together with dryness and fiery meteors in the air,pestilence, and venomous snakes. Lastly, the star became like Saturn, and there will finally come a time of want, death, imprisonment and all sorts of sad things.

 * The universe is globe-shaped, either because that is the most perfect shape of all, needing no joint, an integral whole; or because that is the most capacious of shapes, which is most fitting because it is to contain and preserve all...The first and highest of all is the sphere of the fixed stars, which contains itself and all things, and is therefore motionless. It is the location of the universe, to which the motion and position of all the remaining stars is referred. For though some consider that it also changes in some respect, we shall assign another cause for its appearing to do so in our deduction of the Earth's motion. There follows Saturn, the first of the wandering stars, which completes its circuit in thirty years. After it comes Jupiter which moves in a twelve-year long revolution. Next is Mars, which goes round biennially. An annual revolution holds the fourth place, in which as we have said is contained the Earth along with the lunar sphere which is like an epicycle. In fifth place Venus returns every nine months. Lastly, Mercury holds the sixth place, making a circuit in the space of eighty days. In the middle of all is the seat of the Sun. For who in this most beautiful of temples would put this lamp in any other or better place than the one from which it can illuminate everything at the same time? Aptly indeed is he named by some the lantern of the universe, by others the mind, by others the ruler. Trismegistus called him the visible God, Sophocles' Electra, the watcher over all things. Thus indeed the Sun as if seated on a royal throne governs his household of Stars as they circle around him. Earth also is by no means cheated of the Moon's attendance, but as Aristotle says in his book On Animals the Moon has the closest affinity with the Earth. Meanwhile the Earth conceives from the Sun, and is made pregnant with annual offspring. We find, then, in this arrangement the marvellous symmetry of the universe, and a sure linking together in harmony of the motion and size of the spheres, such as could be perceived in no other way. For here one may understand, by attentive observation, why Jupiter appears to have a larger progression and retrogression than Saturn, and smaller than Mars, and again why Venus has larger ones than Mercury; why such a doubling back appears more frequently in Saturn than in Jupiter, and still more rarely in Mars and Venus than in Mercury; and furthermore why Saturn, Jupiter and Mars are nearer to the Earth when in opposition than in the region of their occultation by the Sun and re-appearance. Indeed Mars in particular at the time when it is visible throughout the night seems to equal Jupiter in size, though marked out by its reddish colour; yet it is scarcely distinguishable among stars of the second magnitude, though recognized by those who track it with careful attention.
 * Nicolaus Copernicus on the Revolution of the Heavenly Spheres quoted in: Károly Simonyi A Cultural History of Physics, CRC Press, 25 January 2012, p. 180


 * We find then in this arrangement an admirable harmony of the world, and a dependable, harmonious interconnexion of the motion and the size of the paths, such as otherwise cannot be discovered. For here the penetrating observer can note why the forward and the retrograde movement of Jupiter appears greater than that of Saturn, and smaller than that of Mars, and again greater with Venus than with Mercury; and why such retrogression appears oftener with Saturn than with Jupiter, less often with Mars and Venus than with Mercury. Moreover, why Saturn, Jupiter, and Mars, when they rise in the evening, appear greater than when they disappear and reappear [with the sun]...And all this results from the same cause, namely the motion of the earth.

 * In awe, I watched the waxing moon ride across the zenith of the heavens like an ambered chariot towards the ebony void of infinite space wherein the tethered belts of Jupiter and Mars hang, for ever festooned in their orbital majesty. And as I looked at all this I thought... I must put a roof on this toilet.

They're being done continuously by cosmic rays hitting our astronomical bodies, like the moon, the sun, like Jupiter and so on and so forth. And the earth's still here, the sun's still here, the moon's still here. LHC collisions are not going to destroy the planet.

 * But what exceeds all wonders, I have discovered four new planets and observed their proper and particular motions, different among themselves and from the motions of all the other stars; and these new planets move about another very large star [Jupiter] like Venus and Mercury, and perchance the other known planets, move about the Sun. As soon as this tract, which I shall send to all the philosophers and mathematicians as an announcement, is finished, I shall send a copy to the Most Serene Grand Duke, together with an excellent spyglass, so that he can verify all these truths.

 * I therefore concluded, and decided unhesitatingly, that there are three stars in the heavens moving about Jupiter, as Venus and Mercury about the Sun; which at length was established as clear as daylight by numerous other observations. These observations also established that there are not only three, but four, erratic sidereal bodies performing their revolutions round Jupiter.

 * Galileo claimed to have seen mountains on the Moon, to have proved the Milky Way was made up of tiny stars, and to have seen four small bodies orbiting Jupiter. These last, with an eye to getting a position in Florence, he quickly named 'the Mediciean Stars. But when all was finished, no one besides my brother could get a glimpse of Jupiter or Saturn, for the great length of the tube would not allow it to be kept in a straight line. This difficulty, however, was soon removed by substituting tin tubes.

 * I shall explain a System of the World differing in many particulars from any yet known, answering in all things to the common Rules of Mechanical Motions: This depends upon three Suppositions. First, That all Cœlestial Bodies whatsoever, have an attraction or gravitating power towards their own Centers, whereby they attract not only their own parts, and keep them from flying from them, as we may observe the Earth to do, but that they do also attract all the other Cœlestial bodies that are within the sphere of their activity; and consequently that not only the Sun and Moon have an influence upon the body and motion the Earth, and the Earth upon them, but that Mercury also Venus, Mars, Saturn and Jupiter by their attractive powers, have a considerable influence upon its motion in the same manner the corresponding attractive power of the Earth hath a considerable influence upon every one of their motions also. The second supposition is this, That all bodies whatsoever that are put into a direct and simple motion, will continue to move forward in a straight line, till they are by some other effectual powers deflected and bent into a Motion, describing a Circle, Ellipse, or some other more compounded Curve Line. The third supposition is: That these attractive powers are so much the more powerful in operating, by how much the nearer the body wrought upon is to their own Centers. Now what these several degrees are I have not yet experimentally verified; but it is a notion, which if fully prosecuted as it ought to be, will mightily assist the Astronomer to reduce all the Cœlestial Motions to a certain rule, which I doubt will never be done true without it. He that understands the nature of the Circular Pendulum and Circular Motion, will easily understand the whole ground of this Principle, and will know where to find direction in Nature for the true stating thereof. This I only hint at present to such as have ability and opportunity of prosecuting this Inquiry, and are not wanting of Industry for observing and calculating, wishing heartily such may be found, having myself many other things in hand which I would first complete and therefore cannot so well attend it. But this I durst promise the Undertaker, that he will find all the Great Motions of the World to be influenced by this Principle, and that the true understanding thereof will be the true perfection of Astronomy.

 * For the planets round about him (the Sun), as though he were their king, lead on their dance, at appointed distances pursue their orbits at the utmost harmony....If, however, he should have nothing in common with them, except this power of doing good, which communicates unto all, then we ought to acquiesce in the reasoning of the Egyptian priests, who raise altars to the Sun conjointly with Jupiter ; nay, rather we should assent to Apollo himself (long before them), who sits on the same throne with Jove, and whose words are, " One Jove, one Pluto, one Sun is Serapis. From which we must conclude that the sovereignty of the Sun and of Jupiter amongst the deities that are objects of intellect is held in common, or rather is one and the same.

 * The orbit of the earth is a circle; round the spheres to which this circle belongs describe a dodecahedron; the spheres including this will give the orbit of Mars. Round Mars describe a tetrahedron; the circle including this will be orbit of Jupiter. Describe a cube round Jupiter’s orbit; the circle including this will be Saturn. Now, inscribe in the earth’s orbit an icosahedron, the circle inscribed in it will be the orbit of Venus: inscribe an octahedron in the orbit of Venus: the circle inscribed in it will be Mercury’s orbit. This is the reason of number of planets.

 * The earth's becoming at a particular period the residence of human beings, was an era in the moral, not in the physical world, that our study and contemplation of the earth, and the laws which govern its animate productions, ought no more to be considered in the light of a disturbance or deviation from the system, than the discovery of the satellites of Jupiter should be regarded as a physical event in the history of those heavenly bodies, however influential they may have become from that time in advancing the progress of sound philosophy among men.

 * The word planet comes from the Greek for “wanderer,” because the planets' positions change relative to those of the stars. The eight (formerly nine) recognized planets that orbit the Sun are, in order of increasing distance, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The first four are called terrestrial planets and the next four giant, or Jovian, planets.

 * That the squares of the periodic times are proportion to the cubes of the major-axes. These laws were discovered by Kepler from observations made on Mars and stated by analogy as general laws, which, although not rigidly true, are sufficiently near to the truth to have led to the discovery of the law of attraction of the bodies of the solar system. The deviation from complete accuracy is due to the facts, that the planets are not of inappreciable mass, that, in consequence, they disturb each other's orbits about the Sun, and, by their action on the Sun itself, cause the periodic time of each to be shorter than if the Sun were a fixed body, in the subduplicate ratio of the mass of the Sun to the sum of the masses of the Sun and Planet; these errors are appreciable although very small, since the mass of the largest of the planets, Jupiter, is less than 1/1000th of the Sun's mass.

 * The Spirits survey the heavens and the earth and all the harmonious motions of the universe. They see the heavenly bodies set in revolving whorls, which, whorl within whorl, combine to form the Spinning-whorl on the Spindle of Necessity; and the Goddess holds the spindle on her knee, and spins the thread which the Fates wind, unwind and cut. The heavenly bodies, or the spheres or whorls in which they lie, are arranged one within another in the following order: 1. The Fixed Stars. 2. Saturn. 3. Jupiter. 4. Mars. 5. Mercury. 6. Venus. 7. The Sun. 8. The Moon. This order is as good as any other that can be framed under a geocentric hypothesis

 * As the whorls differ from one another in respect of “ breadth of rim”, the first and outermost whorl is that which has its circular rim the broadest, and the sixth whorl comes next to it in regard to breadth of rim; and, proceeding in order of breadth, the fourth whorl comes third, and the eighth fourth, and the seventh fifth, and the fifth sixth, and the third seventh, and the second eighth.' Thus we have now a new classification of the heavenly bodies, in the following sequence: 1. The Fixed Stars. 2. Venus. 3. Mars. 4. The Moon. 5. The Sun. 6. Mercury. 7. Jupiter. 8. Saturn.

 * Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilinear; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas.

 * Jupiter, the biggest planet in our solar system is called as 'Guru Graham' in Sanskrit. This planet is related to the intellect of humans. Hence it is called as Guru (Budha Graha). The planet Jupiter, changes from one Raashi (12 astrological signs. Aries, Taurus, etc) to another every year. During the period of retrograde it slows down but still it makes up for the slowness and on an average it changes the Raashi house every year. This change generally happens in the last week of the month December. This type of calendar system is connected with the movement of the Sun and is called as Solar Calendar.

 * The Pythagorean harmony of the spheres lives on to this day. In his Natural History (circa AD77), the Roman scientist and noble man Pliny the Elder considered formed by the earth and Moon to be a tone; Moon to Mercury a semi-tone; Mercury to Venus, a semi-tone; Venus to the Sun, a minor third; Sun to Mars, a tone, Mars to Jupiter, a semi-tone; Jupiter to Saturn, a semi-tone; and Saturn to the fixed stars, a minor third. The 'Pythagorean Scale' created from this musical arrangement is still recognised. And Pliny's report reveals not only a heavenly musical scale, but also a Cosmic architecture that was to have a profound influence on the history of astrobiology. The story goes that only the master, Pythagoras, was graced with the gift of actually hearing this harmony of the spheres.

 * To the ancient eye, without the use of spyglass, only seven of these ‘wanderers’ or ‘planets’ as they were known, could be seen among the thousands of lights that bejewelled the firmament. The 'Wanderers' were different. True, like the fixed stars, the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn all seemed to revolve once a day around the Earth. But the Plants also had a peculiar motion.

 * ...cosmos was complete. Its out limit was the stellar sphere. Just inside was Saturn, since it was the planet that took longest to move around the Zodiac. Next came Jupiter and Mars, set in order of decreasing orbital period, the time taken to make one complete orbit about the central Earth. Innermost was the Moon, since the lunar orbit placed it closest to us. The remaining three planets of Sun, Venus and Mercury, posed a problem. All three vagabond stars made their seeming journey about the Earth, in the same common time of one year.
 * In: p. 11


 * The term ‘superior planet’ was used by those bodies (Mars, Jupiter, and Saturn) that lay behind the Sun’s orbit. The system gave no idea of the sheer size of the orbits, and no account of inconsistencies of the planets in their apparent motion. But these mathematical features were to develop later.
 * In: p. 11


 * The great man [Galileo in 1610 on 24 and 25 April] was asked to demonstrate the Jupiter moons in the spyglass. Not one among the eminent guests was convinced of their existence. The crude nature of the mysterious gadget did not help. But many were blinded by bias — they refused to look down the tube...Kepler was the only weighty voice raised in defense...The revolution in science begins with the discovery of these ‘alien’ worlds and the names of Galileo and Kepler have come to symbolize that revolution.
 * In: p. 74


 * Back in 1610, perhaps the greatest discovery Galileo had made with the spyglass was the essentially four new worlds in the Jupiter system. The four new planets were the first four moons of Jupiter their significance to the case of Copernicanism was set up by Galileo. The moons in orbit around Jupiter also exposed the ancient fallacy that the earth was the center around which all revolved.
 * In: p. 105


 * He discovered the moons of Jupiter, the phases of Venus, the terrestrial nature of the [[Moon, and thousands upon thousands of stars never picked out before. Galileo's findings provided immense impetus to the Copernican viewpoint on the cosmos and also boosted Atomist speculation. May be this universe is, as the Atomists said, a cosmos vast in scale, perhaps even infinite, and abundantly seeded with life throughout.

 * That the planets are not without Water, is not made probable by the late observations: For about Jupiter are observed some spots of a darker hue than the rest of his Body, which by their continual change show themselves to be Clouds...Mars too is found not to be without his dark spots... but whether he has clouds or no, we have not had the same opportunity of observing as in Jupiter. Since ‘its certain  that Earth and Jupiter have their water and clouds, there is no reason why the other Planets should be without them. I can’t say that they are exactly of the same nature with our Water, but they should be liquid their use requires, as their beauty does that they should be clear. For this Water of ours, in Jupiter or Saturn, would be frozen up instantly for  reason of the vast distance of the Sun. Every Planet therefore must have its Waters of such a temper as to be proportione’d to its heat.
 * In: p. 111
 * Huygens was aware of the fact that the kind of water found on Earth would instantly freeze on Jupiter, and vaporize on Venus.He observed dark and bright spots on the surface of some of the planets, such as Mars and Jupiter, and suggested that the spots could only be justified by the existence of water and ice on those worlds.


 * Attendants of Jupiter and Saturn are of the same nature with our Moon, as going round them, and being carry'd with them round the Sun just as the Moon is with the Earth. Their Likeness reaches to other things too,...Therefore whatsoever we can with reason affirm or fancy of our Moon must be supposed with very little alteration to belong to the Guards of Jupiter and Saturn, as having no reason to be at all inferior to that.
 * In: p. 112


 * If the Moon is not inhabited, as observations suggest based on the absence of water and an atmosphere, this says little about life on other worlds, save for those of similar rank, i.e., other moons. Which means that other planets, especially those superior and majestic worlds, such as Saturn and Jupiter, should be equal in all ways to the Earth, intelligent inhabitants included.
 * In: p. 112


 * Featured in his Celestial Scenery (1837), Dick discusses the cosmos, as seen from Mars, Jupiter, the planetoids, and beyond. Using a method similar to that of Huygens, Dick takes the topic further still, allotting populations to all the planetary bodies of the solar system, and even for the rings of Saturn, a rather arresting idea.

 * Surely no astronomer worthy the name can regard this grand orb as the cinder-centred globe of watery matter so contemptuously dealt with by one who, be remembered thankfully was not an astronomer...Jupiter in a sense a Sun...a source of heat which serves its satellites on which life – even such forms of life as we are familiar with – may still exist...[the gas giant] must be intended one day the abode of noble races.

 * William Whewell's, position on Jupiter was indicative.


 * Each planet, according to its dimension, has a certain length of planetary life, the youth and age of which include the following eras :- a Sun like state; a state like that of Jupiter or Saturn, but when much heat but little light is evolved; a condition like that of our earth; and lastly, the stage through which our Moon is passing, which may be regarded as planetary decrepitude.
 * Proctor in: p. 185


 * Proctor had banished Solar system life from any moon or planet other than Earth. On Mars it had disappeared, though, 'the development of higher forms of life may have been less complete than on our earth'. Jupiter lay in wait. Lifeless still, it was evolving an enabling habitat, one that would embrace 'creatures far higher in the scale of being than any that have inhabited, or may inhabit, the earth. For Proctor, in time even the Sun will harbour life.
 * In: p. 185


 * Rather under-represented in moons, petite in mass and magnitude, Earth does not fare well in comparison with gas giants Jupiter and Saturn, and especially the Sun. Rejecting the idea the giant planets are poorly placed, Flammarion even so admits atmospheres of other plants are ‘essentially different’, from those on Earth, as there is no evidence extant to show they are ‘of a chemical composition analogous to our planet.
